I see, you've been using part of Swing's API to traverse the tree.
Don't your domain objects of the tree know their parents? If not, you
may be able to walk up the Wicket component tree to the parental tree
item to get the parent domain object.
What do you use this for? What's your usecase?

I am still using the deprecated tree and am building the new tree in a
sandbox, so I am able to put the update on hold if there is a good
solution on the way in the next few weeks. We are attempting to move
to the new tree so that we are not having to scramble once the
deprecated methods are removed. In 1.5, I am extending
DefaultMutableTreeNode and the tree model took care of setting up the
the next and previous nodes. I was able to call
DefaultMutableTreeNode#getPreviousNode() to get the previous node. I
still had to write more complex logic to move up through parent nodes
when my selected node was index 0.
For now, I am adding the parent node and its children to each tree
node object after sorting it in ITreeProvider#Iterator<? extends T>
getChildren(T node);. Once that happens, I can grab the parent from
the selected node and move through the children via indexes. I tried
just moving through the nodes in my data cache in the provider, but
that created a problem as the data cache is not sorted and I am using
ISortableTreeProvider to do that work. I may be going about this the
right way for what I need, but it seems to me that I am making it
harder than it should be.
Thanks for any help!

Hi,
when do you need this information? How did you do it in 1.5?

I am updating my trees from Wicket 1.5 to 6.2. I need to get the
next node and previous node related to the node the user has
selected. I am using a NestedTree similar to
http://wicket-tree.appspot.com/nested (set Content to
SelectableFolderContent). Is there an easy way to do this?
